A particular particle physics scenario (alternative to low-energy supersymmetry) that has been a special focus of interest is the one introduced by Randall and Sundrum (see the white paper [1]}).
In this scenario, a slice of a highly warped 5d space-time is used to explain the hierarchy; the Standard Model Higgs fields can naturally live in the region of small warp factor. Such warped geometries are common in examples of AdS/CFT, and a dual description of their scenario involves a (cut-off) conformal field theory coupled to gravity.
This scenario may enjoy a natural home in string theory: fluxes can give rise to significant warping, and for this reason large hierarchies of scales are easily accessible in warped regions of string compactifications. There has been a large body of research on this, and should data indicate it to be a leading scenario in particle physics going forward, one can anticipate continued development.
